Lever 12 will then be free to move and, under the action of spring 13 will oscillate to the opposite extreme position until pin 26 enters opening 24 in the latch. When the movement in the opposite direction takes place, boss 28 on lever 11 comes into playand moves the latch 22 so as to actuate slide-valve 9 to its opposite extreme postion.

Another valve reversing mechanism is shown in Fig. 5 which comprises a pair oflevers l1 and 12 similar to the preceding onesfmounted on a shaft 13 and connectet together by a spring 13 and "to members 7 and 1 4, respectively. The lever 11 "carries a cam element 29 having its lower surface concentric with theshaft 13. A T-shaped member 30 is pivotall'y-mounted on a shaft 3l'fixed with respect to the frame and extenoing' parallel to shaft 13. The upper or horizontal bar of'the T, duringthe movement of the piston rod 7, .bears against the cam surface 29 and the T isthus prevented from movement. Thedownwardly extending or vertical bar of the T constitutes'a lug'to retain-the lever 12against movement, even though the spring '13 tends to draw this member 12 in the direction ofand after the lever 11. Balanced springs 32, 32 are connected to {the downwardly extending bar of the T toreturn it after actuation tothe position of Test as shown in Fig. 5. The various parts cooperate to function as follows: When the levers ll'and 12-(and also the pump andcompressor pistons) are adjacent one extreme position, being the left hand one in Fig. 5, the upper surface of the horizontal bend of the T will fit against the curved surface of 'c'am'29 on lever 11, and the body of movement, so that the downwardly extends ing lug of. the T member will prevent a movement of the lever 12 when the piston rod 7 moves toward the right. This movement of the lever 11, however, will act through the spring 13 to produce a tendency of the lever 12 to rock clockwise about the shaft 13. lever 12, however, is held at rest, by this lug until the lever 11 has moved so far toward the right in a clockwise direction that the curved surface of cam 29 has passed from above the horizontal bar of the T member 30. The pull of spring 13then upsets the balanced eflects of the spring 32, and the T member 30 rocks counterclockwise about its pivot 31, thusreleasing the lever 12 which is snapped quickly in a clockwise direction,

moving the valve rod 14 to'shift the reversing valve as before. As soon as the lever 12 has cleared the T member 30, the'latter is returned by its balanced springs 32,32, to the positionshown in Fig. 5, and as soon as the piston rod 7 moves toward the'left again, the lever 12 (this time at theleft hand upper corner of the lever) is prevented from fol-' lowingthe-lev er .11 until the lever 11 has The In-another form of valve reversing mechanism shown in'Fig. 6, the stem 14-of-the slidevalve is provided with 'a bent portion or arm 33 and rod 7"wi tha lateral .pin'34. Element 35 is interposed 'between-members33 and 34 and is tiltably mounted on shaft 36 parallel to elements 7 and 14. VVhein the rods 7 and 14reach extremeposition, member 35 is held at rest by pin 34 and, by means of an arm 37 abutting against whichiis under the action of spring 13 :ho1ds the stem 14 at rest.

Vhen rod 7 begins the'move 'toward its other, extreme position, pin 34 causes element 35' to tilt on shaft 36 through the intermediary of a cam 38 formed on 35. Arm 37 thenre leases arm 33 and s'tem-14,-under the action ofspring 33, quickly executes the reversing movement. /Vhen rod 7 moves in the opposite direction the apparatus r'eassu'mes its original position.

In the reversing mechanism shown in Figs. 7, '8 'and 9,rods 7 and 14are arranged to be parallel and relatively clo'se'to one another. The two rods slide in a .pair of slide-ways formed in ablock 39 andhavetheir extremities shaped to form the upper and lower halves, 40 and "41-,of a chamber carrying a compression spring 42. A ball 43 having'a diameter slightly greater than the distance betweenrods' 7 and 14 is introduced into the body of block-39and pairs 'of'spherically shaped notches-44, 45an'd 46, 47 are formed i in rods 7 and 14'r'espectively.

Wh'en 'rod' 7 finally arrives at its extreme position, notch 45 comes opposite the ball-and the latter being now between two notches ize; 45' and 46, releases rod 14. The 1 latter; underthe pressure of spring 42 then quickly executes the reversing movement in thdirection' takenby rod 7 9), and notches 47and46 comeinto position-opposite ball43; When'ro'd 7 moves in the opposite" direction, rod 14 is again held inp'osition until rodf'7"reaches the end of its course and is then released to take 'up its original position shown in Fig. 7.- Ball-43, it is to be understood, can be replaced by other mecha-,
